  A series of novel 7-deazapurine ribonucleosides bearing an alkyl, aryl, or lietaryl group in position 6 and H, F, or Cl atom in position 7 has been prepared either by Pd-catalyzed cross-coupling reactions of the corresponding protected 6-clilot-o-(7-h ilogeiiztted-)7-deiz ipurine ribonucleosides with alkyl- or (het)arylorganometallics followed by deprotection, or by single-step aqueous phase cross-coupling reactions of unprotected 6-chloro-(7-lialogen tted-)7-de iz tl)tii-iiie ri bon ucleos ides with (het)arylboronic acids. Significant cytostatic effect was detected With a Substantial proportion ofthe prepared compounds. The most potent were 7-H or 7-17 derivatives of 6-furyl- or 6-thienyl-7-deazapurines displaying cytostatic activity in multiple cancer cell lines with a geometric mean of 50% growth inhibition concentration ranging from 16 to 96 nM, a potency comparable to or better than that of the nucleoside analogue clofarabinc. lntr icel]Lll ll'pliosphoi-yl itioil to niono- and triphosphates and the inhibition of total RNA synthesis was denionstrated in preliminary study of metabolism and tinechanistin of action Studies.
• Structure−Activity Relationships of 7-Deaza-6-benzylthioinosine Analogues as Ligands of<i>Toxoplasma gondii</i>Adenosine Kinase

  Several 7-deaza-6-benzylthioinosine analogues with varied substituents on aromatic ring were synthesized and evaluated against Toxoplasma gondii adenosine kinase (EC.2.7.1.20). Structure-activity relationships indicated that the nitrogen atom at the 7-position does not appear to be a critical structural requirement. Molecular modeling reveals that the 7-deazapurine motif provided flexibility to the 6-benzylthio group as a result of the absence of H-bonding between N7 and Thr140. This flexibility allowed better fitting of the 6-benzylthio group into the hydrophobic pocket of the enzyme at the 6-position. In general, single substitutions at the para or meta position enhanced binding. On the other hand., single substitutions at the ortho position led to the loss of binding affinity. The most potent compounds, 7-deaza-p-cyano-6-benzylthioinosine (IC(50) = 5.3 mu M) and 7-deaza-p-methoxy-6-benzylthioinosine (IC(50) = 4.6 mu M), were evaluated in cell culture to delineate their selective toxicity.
